The SR4G031 (Robusta) from Antenova is an antenna that operates from 1559 to 1609 MHz. This linearly polarized antenna delivers a peak gain of -0.5 dBi with an efficiency of more than 45%. The self-adhesive antenna measures 23 x 16 x 1.7 mm and is available with 150/200/250 mm cable length options. This antenna is ideal for smart meters, smart lighting and tracking moving objects. While antennas are usually positioned away from metal surfaces to prevent reflections, this antenna has been optimized to radiate on metal surfaces. The design of this antenna allows it to maintain its performance, without de-tuning, when it is mounted on various surfaces, including metal.
